DETAILED DESCRIPTION

As mentioned above, inventory management systems are typically used to manage items stored at various locations. Transactions that are associated with the receipt, dispatch, or transfer of items are often entered into the inventory management system as an inventory line. The inventory line includes identifying information of an item such as identification numbers and names, the quantity of items to be moved, and the current storage location items of those items.

In some cases, an inventory line entry requests the movement of items from a particular storage location that does not have enough of those items to meet the requested quantity. It may also be the case that other storage locations hold the quantity requested. In this case, multiple inventory lines can be created to replace the initial inventory line. These multiple inventory lines will each have different storage locations and quantities. The sum of the quantity from each storage location will be enough to meet the requested quantity from the initial inventory line.

The present specification discloses methods and systems that provide a single user interface to allow a user to handle a situation where the requested number of items within an inventory line entry cannot be met and multiple line entries need to be created in its place. This single user interface provides the user with the ability to automatically create the new inventory lines and manually adjust the automatically created inventory lines. Furthermore, the user is provided with other options such as adjusting the originally entered inventory line. All of these features are provided in a single user interface window. This provides flexibility and efficiency for the management of the inventory under the control of the inventory management system.

As will be appreciated by one skilled in the art, aspects of the present invention may be embodied as a system, method or computer program product. Accordingly, aspects of the present invention may take the form of an entirely hardware embodiment, an entirely software embodiment (including firmware, resident software, micro-code, etc.) or an embodiment combining software and hardware aspects that may all generally be referred to herein as a “circuit,” “module” or “system.” Furthermore, aspects of the present invention may take the form of a computer program product embodied in one or more computer readable medium(s) having computer readable program code embodied thereon.

Any combination of one or more computer readable medium(s) may be utilized. The computer readable medium may be a computer readable signal medium or a computer readable storage medium. A computer readable storage medium may be, for example, but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any suitable combination of the foregoing. More specific examples (a non-exhaustive list) of the computer readable storage medium would include the following: an electrical connection having one or more wires, a portable computer diskette, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or Flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing.

Throughout this specification and in the appended claims, the term “computerized inventory management system” is to be broadly interpreted as a system that includes hardware and software to provide a user with inventory management application functions.

Throughout this specification and in the appended claims, the term “bin” refers to a specific location at which an item may be stored. A bin may include a geographical location as well as a specific container or shelf to hold an item.

Referring now to the figures, FIG. 1 is a diagram showing an illustrative computerized inventory management system (100). According to certain illustrative examples, the inventory management system (100) includes a memory (102) having software (104) and data (106) stored thereon. The physical computing system (100) also includes a processor (108) and a user interface (110).

There are many types of memory available. Some types of memory, such as solid state drives, are designed for storage. These types of memory typically have large storage volume but relatively slow performance. Other types of memory, such as those used for Random Access Memory (RAM), are optimized for speed and are often referred to as “working memory.” The various forms of memory may store information in the form of software (104) and data (106).

The inventory management system (100) also includes a processor (108) for executing the software (104) and using or updating the data (106) stored in memory (102). The software (104) may include an operating system. An operating system allows other applications to interact properly with the hardware of the mobile computing system. The other applications may include inventory management software. The data (106) may include inventory lines that are stored in a format to be used by the inventory management application.

A user interface (110) may provide a means for the user (112) to interact with the physical computing system (100). The user interface may include any collection of devices for interfacing with a human user (112). For example, the user interface (110) may include an input device such as a keyboard or mouse and an output device such as a monitor. As will be described in more detail below, the user interface may provide a specific user interface such as a split quantity user interface. The split quantity user interface provides the user with tools to handle situations where requested transactions are not able to be completed based on the entry of a single inventory line.

FIG. 2 is a diagram showing an illustrative split quantity user interface (200) for an inventory management system. According to certain illustrative examples, the split quantity user interface includes a header section (204), a control section (206) with an autosplit control (210) and a manual control (212), and an inventory lines section. In some cases, the split quantity user interface (200) appears in the form of a window (202) in response to a user entering a line that is not able to be processed. For example, a user enters a line into the inventory management system that requires 20 widgets to be taken from a particular bin. However, that bin only contains 15 widgets. Therefore, that line is not able to be processed. To meet the request, at least two lines should be entered into the system. One line will request 15 widgets from the originally requested bin and another line will request the remaining five widgets from a different bin. However, the user may not have knowledge of the quantity available in each bin that holds the requested widget.

The header section (204) will display information related to the originally entered inventory line to the user. This originally entered inventory line will be referred to as the initial inventory line. More detail about the header section will be discussed below in the text accompanying FIG. 3.

The control section (206) provides a number of tools to the user to handle the split quantity situation. One such tool is an autosplit control (210). The autosplit control (210) will automatically create new inventory lines to replace the initial inventory line. Using the above example, the new inventory lines will include a first inventory line requesting 15 widgets from a first bin and a second inventory line requesting the remaining 5 widgets from a second bin.

In some cases, the autosplit control (210) may operate under a set of constraints. For example, there may be several bins that store a particular item. These bins may have a ranking that indicates which bins should be exhausted before items can be removed from another bin. In some cases, the constraint may be alphabetical. Furthermore, some constraints may specify a minimum number of items to be left in a bin.

The manual control (212) allows the user to manually adjust the newly created inventory lines. For example, the user may wish to take the 5 remaining widgets from a third bin. Thus, the user may manually change the bin for the second inventory line to the third bin, in some cases, there may not be a specific manual control to allow manually adjustment. Rather, the user can simply make the adjustments directly to the inventory lines displayed in the inventory lines section (208).

The inventory lines section (208) displays the lines that will be created when the user is done with the split quantity dialog window (202). For example, when the user interface (202) first appears, the inventory lines section (208) may only display the initial inventory line that was entered by the user. After the user engages the autosplit control (210), the inventory lines section (208) may display the newly created inventory lines that will replace the initial inventory line.

FIG. 3 is a diagram showing an illustrative header section (300) of a split quantity user interface. As mentioned above, the header section (300) displays information related to the initial inventory line entered by a user. For examples, the header section (300) may include an item number (302), an item name (304), a bin (306), a quantity requested (308), a quantity available (310), and a total number available (312). Additionally, the header section (300) may include an adjust line entry control (214) to allow a user to manually adjust information associated with the initial inventory line.

Inventory management systems often keep track of items by assigning an item a number (302) in addition to the item name (304). This number is often referred to as a Stock Keeping Unit (SKU) number. In some cases, the SKU number may be a proprietary number assigned by a warehouse. In some cases, the SKU is assigned by the manufacturer of the item. Some inventory management systems may use both manufacturer and warehouse defined SKU numbers.

The bin (306) indicates the location of the requested item. A bin is typically assigned a number by the warehouse or entity in control of the inventory. The bin number specifies the location of a particular item. In some cases, a bin number is coded based on the location of the bin. For example, a bin number may be coded so as to indicate a particular aisle, row, shelf and even geographic location.

The quantity requested (308) shows the number of items requested from the requested bin in the initial inventory line. In some cases, a user does not need to enter a specific bin. Rather, a particular item may have a default primary bin. The quantity available (310) indicates the present number of items in the requested bin. This quantity available will presumably be less than the quantity requested because the split quantity dialog box appears in response to this particular situation.

The total available (312) shows the user the total number of items controlled by the entity operating the inventory management system. This allows the user to readily determine whether or not the requested quantity of items is even possible to meet. In some cases, an additional box or window may appear that informs the user of this specific situation. In this situation, the user may use the adjust line entry control (314) to change the quantity requested so that it is less than the total available (312).

The inventory management system may record certain changes made to the header section (300). The inventory management may then inform the proper personnel of the situation. For example, if the initial inventory line corresponds to a request from a customer to purchase a certain number of items and the entity operating the inventory management system does not currently have the total number on hand, then the appropriate sales person may be informed of this situation. The sales person can then inform the customer and work out a different deal.

In the example illustrated in FIG. 3, the initial inventory line includes a request for 34 widgets. However, only 20 widgets are available in the requested bin. Furthermore, there is a total of 41 available widgets, some of which are stored in other bins. Because, the total available still exceeds the quantity requested, the user does not need to make a change to the header section. However, the user may still make a change if so desired. For example, the user may wish to reduce the quantity requested so as to leave a certain amount of widgets in storage. Whether or not the user makes any changes, he or she will then go to the inventory lines section to manage the creation of new inventory lines to replace the initial inventory line.

FIG. 4A is a diagram showing an illustrative inventory lines section (400) of a split quantity user interface. As mentioned above, the inventory lines section (400) can display the new multiple lines that are created to replace the initial inventory line. The inventory lines (402) shown in FIG. 4 may have been created either manually or by using the autosplit control (e.g. 210, FIG. 2). According to certain illustrative examples, the inventory lines (402) may include an item number column (404), an item name column (406), a bin column (408), a quantity column (410), and a remain column (412).

In general, the item number (404) and item name (406) for each of the new inventory lines will be the same. However, in some cases, they may be different. For example, some inventory management systems may have different names or numbers for the same items. The different names or numbers of a similar item may correspond to different bins (408).

The bin for each of the new inventory lines (402) will be different for each line. The quantity column (410) of each new inventory line (402) indicates how many items will be taken from that bin to satisfy the original order. The remain column (412) of each new inventory line (402) indicates how many items will remain in that bin when the order corresponding to the new inventory lines is executed.

Continuing the example FIG. 3, the new inventory lines (402) illustrated in FIG. 4 show three inventory lines that are used to replace the initial inventory lines for 34 widgets. 20 of the widgets are taken from bin 12A-3 b, 12 more widgets are taken from bin 27C-4 a, and the remaining two widgets are taken from bin 8E-2 c. Bin 12A-3 b and 27C-4 a would be left with zero widgets, and bin 8E-2 c would be left with 7 widgets.

FIG. 4B is a diagram showing an illustrative inventory lines section of a split quantity user interface after manual adjustment has been made. Whether or not the new inventory lines illustrated in FIG. 4A were created with the autosplit control or manually, the user may manually adjust the inventory lines as desired. For example, it may be the case that the user desires to leave at least 5 widgets in bin 27C-4 a. In this case, the user would adjust the remain column (412) of bin 27C-4 a accordingly. The rest of the new inventory lines (402) may then be automatically updated in accordance with the change made by the user.

In some cases, the item requested may be a rotating item. A rotating item includes both an item number and a specific number unique to each instance of that item. For example, if the item is a laptop, there may be an item number for a particular model of laptop and a unique identification number for each specific laptop. If a particular laptop is to be issued to a particular employee, that transaction may be entered into the inventory management system as an inventory line. In one example, a user may enter an inventory line to issue a laptop to a particular employee and the inventory management system may determine that that laptop is not currently in the requested bin. In this case, the split quantity user interface window will display to the user a number of new inventory lines representing bins for other laptop computers which are available. The user may then select which laptop to issue. The initial inventory line will then be replaced with the new inventory line with the new bin.

The tools, controls, and sections of a split user quantity interface embodying principles described herein are not limited to those described or illustrated. Rather, the above descriptions and associated illustrations give examples of possible user interface characteristics which may be used to provide a user with the ability to effectively handle an inventory line that exceeds the available quantity in the associated bin. Particularly, the user interface provides the user with several tools in a single user interface window.

FIG. 5 is a diagram showing an illustrative method for inventory management. According to certain illustrative examples, the method includes, with an inventory management system, receiving (block 502) a first inventory line comprising an item, a quantity, and a bin, providing (block 504) a split quantity user interface in response to determining that the quantity of the item exceeds an actual quantity stored at the bin, creating and displaying (block 506) multiple new inventory lines to replace the first inventory line in response to an autosplit control of the user interface being engaged, the new inventory lines comprising different bins, and providing (block 508) a control through the user interface to allow manual adjustment of the new inventory lines.

Through use of a split quantity user interface window embodying principles described herein, a user may be provided with a number of tools to efficiently manage inventory lines that request a number of items in excess of an associated bin. These tools are displayed to the user in a single user interface window. Thus, the user does not need to undertake repetitive steps to find which inventory lines are acceptable and which are not. Furthermore, the creation of multiple lines to replace an initial inventory line is highly customizable with additional tools to help a user customize the new inventory lines appropriately.
